1.如何安装Eclipse3.0+lomboz3.01+tomcat5.027？

答：参见以下文章

1) 使用Eclipse3.0+lomboz3.0+jboss3.2.3开发EJB（一）

2) Eclipse 3 + Lomboz 3 + Tomcat 5 开发网站

2.安装lomboz时，按要求将所需文件解压到了plugin目录下，可是打开eclipse并没有找到相关的选项为什么？

答：

第一种方法：This is because of cached eclipse plugin/feature information. The solution is simple - Start eclipse with: eclipse -clean option

第二种方法：删除configuration/org.eclipse.update目录，重启eclipse

第三种方法：Having troubles with installing Lomboz 3.0? Just follow the steps below:

1. Remove your Eclipse folder completely 2. Unzip Eclipse 3. Do not run Eclipse at this stage!!!! 4. Unzip EMF 2.0 runtime 5. Unzip Lomboz 3.0 6. Run Eclipse for the first time, and you will be able to configure your Lomboz 3.0

It is very important to note, after you unzip Eclipse, you can't run it after you unzip EMF and lomboz. If you have run Eclipse for the first time before you unzip EMF and lomboz, they will not appear in the 'Customize Perspective' 

3.lomboz配置完成后，启动tomcat不成功，出现Bootstrap: Class loader creation threw exception java.lang.ExceptionInInitializerError，怎么解决？

答：

I edited the file "tomcat50x.server" under C:/eclipse/plugins/com.objectlearn.jdt.j2ee_3.0.1/servers and changed -Djava.endorsed.dirs="${serverRootDirectory}/bin;${serverRootDirectory}/common/endorsed" to -Djava.endorsed.dirs="${serverRootDirectory}/common/endorsed" in the following 'tags': <startVmParameters>-DJAVA_HOME="${jrePath}" -Dcatalina.base="${serverRootDirectory}" -Dcatalina.home="${serverRootDirectory}" -Djava.io.tmpdir="${serverRootDirectory}/temp" -Djava.endorsed.dirs="${serverRootDirectory}/bin;${serverRootDirectory}/common/endorsed"</startVmParameters> and <stopVmParameters>-DJAVA_HOME="${jrePath}" -Dcatalina.base="${serverRootDirectory}" -Dcatalina.home="${serverRootDirectory}" -Djava.io.tmpdir="${serverRootDirectory}/temp" -
